Constantly running into issues with our WatchGuard XTM505. Easily my least favorite piece of equipment in our inventory. We've had numerous occasions where the XTM505 would lose it's configuration without warning; no power surge, no tampering, nothing. I personally find that the documentation and support from WatchGuard is sub-par as well.

The Core of a Solid Secure Network. Tons of VPN through put, no latency here. The WSM management software makes it super easy to maintain. Along with the Centralized management Console, you maintain your entire network form one spot. All based on The XTM 5 Device, we run a XTM 530, with large VPN network. We have zero issues with any of it.

Great product for SMB. We have fluxed between 20-60 users and no issues. Rules are easy to set. Easy to manage/report on user activity.
A must piece is the WatchGuard System Server. Makes it so much easier to manage multiple units from single login/interface.
